I went to the toilet one morning and saw there was blood in my pee, so I immediately rang my doctor. I went for tests at the hospital, which showed I had kidney cancer. Because they found it early, it hadn't spread, and they were able to operate successfully.
Acting quickly probably saved my life. In fact, it's given me a new lease of life. I am busier than ever volunteering in my retirement and am planning a big campervan trip around the US with my husband next year.

I noticed blood in my pee in late 2013. I knew something was wrong and made an appointment to see my doctor straight away. He referred me to hospital for tests, which showed I had bladder cancer. I'm so glad I acted quickly and my cancer was caught early. My husband and I enjoy sailing, and six months after my treatment we went sailing around Britain.
You're not wasting anyone's time by getting your symptoms checked out, and if it's not serious, your mind will be put at rest.
At your appointment, your GP may ask about your symptoms, family history and whether you've been exposed to any possible causes of bladder or kidney cancer, such as smoking.
In some cases, your GP may request a urine sample, so it can be tested in a laboratory for traces of blood and bacteria.
Your GP may also carry out a physical examination.
If your doctor suspects cancer, you'll be referred to a hospital for further tests.
